Experimenting with layers allows you to see different images within the context of the entire layout. In addition, you can modify the opacity of a layer and try different blend modes — such as dissolve, lighten, and difference — to see how these effects work with the rest of a design.

You can use the Layers pane of the PSD Import palette to show, hide, blend, and change the opacity of layers within PSD pictures. The PSD Import palette displays information about how the picture file was created, but does not allow you to make fundamental changes to the picture file:

• You cannot create, name, copy, duplicate, align, reposition, delete, or merge layers using the Layers pane.
• If there are no layers in the PSD file, the PSD Import palette shows only the background layer.
